Installing the NC-2000 Patient Unit
3.4.2 Connecting NC-4LED
The NC-4LED corridor light has six wires.
Note:
Third part dome light manufacturers may use low current LEDs or higher current
incandescent lamps. LED dome lights typically range from 5 to 50 mA each, and
incandescent lamps typically range from 50 to 250 mA each. The dome light
relays (CN16) supply up to 500 mA each. Ensure that the dome lights do not
exceed 500 mA each (total of 2.0 A for 4 dome lights).
When calculating the power supply requirements for the Patient Unit, you must
include the power requirements for the dome lights.
For example, with four 24 V incandescent light bulbs at 250 mA each, the
following input currents are drawn by the Patient Unit (at 24 VDC output):
•
Patient Unit maximum current: 25 mA
•
4 dome lights on: 1000 mA
In this example, use a power supply rated at 1.25 A or more.
See section 3.8, Power, on page 27 for more information on power connections.
